REQUIREMENTS 3.1 Materials. All materials used in the manufacture of the initiators shall confor

17、m strictly to the specifications referred to on the respective drawings unless specific approval in writing covering a departure therefrom has been obtained from the cognizant Navy design activity prior to manufacture. When alternate materials or methods of manufacture are specified on the drawings,

18、 the bidders selections shall be clearly stated in the proposal. The remanufactured initiator metal parts assembly shall contain a new shear pin and O-rings. 3.2 Hydrostatic pressure. The initiator chamber and cap shall withstand a hydrostatic pressure of 5500 to 6500 pounds per square inch (psi) fo

19、r 15 seconds, minimum, without deformation or mechanical failure (see 6.3.1). 3.3 Protective finish. Protective finish shall be in accordance with the applicable specifications and drawings and shall apply to all surfaces of the component, regardless of configuration. Remanufactured exterior compone

20、nts shall have the existing protective finish stripped and the specified protective finish reapplied (see 6.3.2). 3.4 Residual magnetism. The metal parts assembly shall not deflect the indicator of the compass more than five degrees in either direction using procedures in 4.5.3. 3.5 Shear pin streng

21、th. The shear pin, after application of protective finish, shall shear when a load of 41 5 pounds is applied at the steady rate of 0.125 inch per minute. 3.6 Metal parts assembly. Parts shall be combined to produce an assembly which conforms to the requirements of the metal parts assembly drawing. A

22、ll threaded joints shall be assembled handtight. 3.6.1 Integrated plant products. When remanufacturing and loading of assembly is performed in an integrated plant, the metal parts assembly requirement may be waived and the residual magnetism requirement performed on the loaded assembly only. 3.6.2 T

23、hreaded component parts. Class 2A or 2B thread gage shall be used on component part inspection versus class 3A or 3B required on remanufactured hardware for initiators. 3.7 Workmanship. The requirements for workmanship are as specified on the applicable drawings, referenced specifications, and the f

24、ollowing: 3.7.1 Metal defects. All components shall be free from cracks, splits, cold shuts, inclusions, porosity, or any similar defect. 3.7.2 Burr. No part shall have a burr which might interfere with the assembly or function of the item or which might be injurious to personnel handling the item.

25、3.7.3 Foreign matter. No part or assembly shall contain chips, dirt, grease, rust, corrosion or other foreign matter.

Reference shall be made to ANSI/ASC A8402 to define the quality assurance terms used. 4.2 Inspection conditions. Unless otherwise specified (see 6.2), all inspections sha

27、ll be performed under the following conditions: a. Temperature: Room ambient 68 to 77F b. Altitude: Sea level c. Humidity: 50 percent relative, maximum d. Atmospheric pressure: 14.7 psia 4.3 Quality conformance inspection. 4.3.1 Lot. 4.3.1.1 Submission of product. Unless otherwise specified by the c

28、ontracting activity, formation and identification of lots shall be in accordance with ANSI/ASQ Z1.4. 4.3.1.2 Size of lot. For the purpose of identification and shipment, the shipping lots of metal parts assemblies shall consist of 600 assemblies, maximum, provided the homogeneity requirements of ins

29、pection lots have been retained. 4.3.2 Examination. On reprocessed parts one-hundred percent examination shall be performed for all critical defects. Examination for major and minor defects shall be performed on a defect basis in accordance with the classification of defects. Four power (4) magnific

30、ation may be used in performing visual examination for such defects as burr and foreign matter. Inspection for rubber O-rings shall be in accordance with MIL-STD-413. When compliance with the applicable requirement is in doubt as a result of visual examination, the characteristics shall be measured

31、or gaged to determine acceptability. All nonconforming material shall be rejected. 4.3.2.1 Examination of reclaimed parts. Examination of reuseable parts, which require no reprocessing, shall be limited to inspection of defects that require visual type inspection. One hundred percent examination sha

32、ll be performed for all such defects. All nonconforming parts shall be reprocessed or rejected. 4.3.2.2 Retainer, Cartridge, Drawing 8594860, covering a detail of Drawing 8594862.
